remember also, some of this crazy cross-breeding is the cause of your hermies! It is in their genes, so to speak.

In answer to your query; you cannot change the sex of a male into anything that will produce anything that you would want to spend a lot of time and money on, to produce something that you wouldn't want to smoke in the first
place...

The growth of seeds ceases the production of resin/thc, and you get an oily bud instead of a resin glazed bud...at least in my experience.
I let them go now, if they are in the middle of flower. That gives the seeds time to mature. This only/mostly happens when growing from seed...imho

Get you a good mother and clone...much safer, higher yield/potency...(throwin'outalinefishbait) and you know what you are getting. Every year start a new batch of seeds and pick a new mother...Flower the old Mother and you will have a tree full of bigbud...sorry, just rambling on...that BBJack is GOOD!!! later.lw
